Sodium carboxymethylcellulose (CMC) is made from natural cotton fibers or wood pulp, through etherification, purification and drying process to made anionic celluslose ether. Whth advanced technology, Our Polyanionic cellulose (PAC) take the advantage of more uniform substitution, which has more superior performance than sodium carboxymethylcellulose (CMC).
Sodium carboxymethylcellulose (CMC) appears as white powder or granules, with good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution.
CMC and PAC can be widely used in Oil drilling, having good water loss control capability, PAC product is a kind of effective water loss controller and viscosifier with high mud yield, strong salt resistance and temperature tolerance.
